I've only ever seen one Triple Lock in person and bought it, but I admit I don't know much about them. I haven't had time to have it lettered, but I was wondering if anyone could please enlighten me in the following areas:

1. I've heard that 5" Triple Locks are less common than other barrel lengths. Does anyone know production by barrel length for this model? This one appears to be factory 5", as all the top barrel markings are centered between the front sight and the frame.

2. Are these stocks correct for the gun? They are unnumbered, but fit it perfectly.

3. Is SN 1451 likely to be first year production? The seller said it was, but didn't have a letter and I've procrastinated on buying the Standard Catalog too long....

Pictures are below. Thanks in advance!
